I wish people could input their own cites and of course other type of dynamic data. e.g water consumption. I guess that kind of dynamic infographic is what Erick Schonfeld was talking about. [1]

I think it's reasonable to assume that we could, if we decided, be much better at using, reusing and conserving our resources. And if we did that, it would be possible for the rest of the world to bring their standard of living up to the US or better, and still not use multiples of the world's available resources.
If that's what we decided.
Worldwide, the best match would be Olt in Romania (http://goo.gl/maps/i8I02) which is precisely 5498km^2
For full-fledged countries, Brunei[1] at 5765km^2

Assuming of course, we don't end up going into space.

Various cycles (CO2, nitrogen, water, soil) are also relatively finite. We've been perturbing several of these for quite some time, with ultimate effects we can't really know.
Not to mention any natural variability within the system.
It would be interesting to see this compared to how much of the world's resources we were using x years ago.
No one knows when Peak Oil will hit or how it will play out, and I'm concerned about it, but I think the long-term outcome is that (a) we'll be fine (although we may get hurt bad by it in the short-term) and (b) objections to nuclear power will vanish. In 50 years, we'll probably be using very cheap, environmentally safe nuclear power, and able to produce food in vertical greenhouses.
The world's population will likely peak around 9.5-10 billion and then begin declining because people are having fewer children.
So I don't think we're in danger of a Malthusian catastrophe, aside from the fact that the developing world is already in one. We're actually coming out of the Malthusian era. Malthus was wrong about the mathematics (economic growth is exponential; it was just so slow-- below 1%-- before the Industrial Revolution that it looked linear) but he was right about the population dynamics of pretty much every pre-industrial society.
> credible plant-based meats in 20 years
What is a plant-based meat? I don't know of any plants with muscles.
Neither you or alexchamberlain actually address his underlying point, so I downvoted you too.
I have chosen to avoid meat substitutes, but I am aware of Quorn. I just didn't read the OPs post like that.
One of the biggest follies of the soy meat industry is trying to make their products healthy by default. Until they may a soy-based animal fat alternative, they don't have a fighting chance of competing. People who truly enjoy meat realize the importance of fatty tissue and how it contributes to flavor.
Go eat a slice of nicely prepared picanha, fat rind and all, and then show me a soy-based product that is even in the same ballpark.
And it still tastes awful.
In fact, if you look at a lot of soy meat substitutes out there, a lot of them are not at all good for you. The whole "soy meat healthier than real meat" thing is pure perception.
What happened here is that one particular luxury (meat) was cherry-picked, out of ideology, and then coated in the veil of population growth and sustenance.
Thats distorting the point, because as the population continues to grow exponentially, any luxury will eventually subside. That can be a car, electricity, a toilet, more than a few square feet for yourself or your basic human rights.
The "populations grow exponentially" argument was state of the art in 1798 [-1], but modern science has taught us that populations grow roughly logistically [0], not exponentially. It's easy to mistake for an exponential in the lower part of the curve (which is all the data we had in 1798), but once you know what to look for, you can see the difference clearly [1].
Of particular note, "exponential growth" means you'll see the same percentage growth rate every year, and larger and larger absolute growth. But what we actually see in humanity is that the percentage growth rate maxed out in the mid 1960s (about 2.2%; it's presently below 1.1%) and the absolute growth rate was at its peak in the late 1980s (88 million in 1989, down to about 75 million now) [2].
Every credible estimate of peak human population puts the number in the 9-12 billion range [3]. That's a lot of people, and will perhaps require some cutbacks, but it's nowhere near the dire levels you predict.

And then we run out of oil. What happens as the mortality skyrockets and humanity downsizes to the new carrying capacity?
It very much matters which it is. It's the difference between stabilizing at 20% more population than we currently have and dealing with a little more overcrowding, and getting so crowded that we don't have toilets any more.
Running out of oil is going to change American lifestyles significantly. I'm not convinced it's going to change global carrying capacity by very much, though. Do you have a credible model that says otherwise? I would like to see such a thing (in its fullest form.)
"Until pressure from a ceiling is applied" is the difference between stabilizing at 9 billion people (a bit more crowded than right now), and growing to so many billions or trillions that the grandparent poster's "no more toilets" prediction would be realistic.
Mince would be easy to make. A real cut of meat (like a rib-eye) would be much harder, but if it's $5/pound for mince "steaks" (patties) and $30/pound for real steaks (massive world-wide demand for tender cuts, but no demand for the tough bits which used to go in hamburgers) then ... well ... people will go for the mince.
And science will eventually give us 100% artificial steaks. Delicious, lab grown meat.

I, for one, welcome our vat-grown replicator meat overlords.
"A green salad," said Arthur emphatically.
"A green salad?" said the animal, rolling his eyes disapprovingly at Arthur.
"Are you going to tell me," said Arthur, "that I shouldn't have green salad?"
"Well," said the animal, "I know many vegetables that are very clear on that point. Which is why it was eventually decided to cut through the whole tangled problem and breed an animal that actually wanted to be eaten and was capable of saying so clearly and distinctly. And here I am."
Eliminating meat is a non-answer, but legally requiring the humane treatment of animals raised for slaughter is a platform that you wouldn't have any difficulty getting most Americans behind were it made a national issue.
The skeptic in me wonders if this is because what you think is humanely raised and slaughtered isn't, really, and plays the rules to earn the label and higher price while only marginally increasing costs.
Alternative terminology can also be used to make high-density confinement sound more palatable. For example: cage-free, free-running, free-roaming, naturally nested, etc. are used as an alternative to the technical term, high-density floor confinement.
Free-range chicken eggs... have no legal definition in the United States.

Demand for animal food products isn't going away and I can't even imagine the changes that would have to take place in society to change that. With that in mind, it seems like you could literally combine a campaign to create farming jobs and treat animals decently during their lives before being slaughtered and served, based on the simple fact that it will require more labor to meet the national demand for meat.
I would love to see an economic study that measures the differences in labor and total cost of production per pound of meat between a factory farm and a humane farm. I expect the costs to be marginally higher, but that the benefits in terms of jobs and humane animal treatment to far outweigh the negatives. If any political candidate wants to base their platform on producing and protecting agrarian jobs I would expect this to be the platform on which to base it. Plant-based agriculture products are never going to return from factory farming, but animal products could.
Just set figures of the percent of meat that needs to be humanely raised reaching 100% in like 10 years. The industry can correct that quickly.
Anyway it is much likelier that we will have labgrown meat, although I guess you would prefer we all go with artificial meat (lab grown meat is real meat, just without the animal. Plant based substitutes are plants).
From what I've read, this isn't cut and dried, so citations would be helpful. Wikipedia links to some meta-study that concluded there was no affect. http://en.wikipedia.org/wiki/Soybean#Men
In any case, there are other plant-based proteins that are not based on soy.
Actually there are places where plants are worse. How do you grow cereals in hot or cold areas or in the mountains? You'll need irrigation for the hot one and harvesting is going to suck in the mountains. There's also the issue of deforestation. Instead it's better to raise animals like chicken, sheep or goats and let them feed with the grass that's available.
Regarding efficiency of plants I've heard that hemp (which is much better than soy) is easy to grow, but I'm not sure about this. Maybe someone else has more information about it.
Animals are incredibly effective in converting widely dispersed plant matter into something we can actually use for energy. Pigs are even probably the world's best recyclers, able to eat anything (garbage, but hopefully just organic left overs), which we can then benefit from indirectly (there is a good reason why many cultures don't eat pork though, its kind of gross when you think too much about it).
There is another interesting story about Coptic Christians in Egypt, pigs, and organic waste collection. The Copts were collecting trash to feed their pigs, but Egypt being mostly Muslim and all told them to kill all their pigs (they were also worried about disease, which could be a valid reason). Anyways, they stopped collecting garbage because no pigs to feed, and the government couldn't supply the garbage collection capacity to fill in the gaps so Cario started smelling very bad. Ah, ecosystems are so fragile and interesting!
